Sorry for indulging but I have some thoughts:
As far as sound quality, I feel like most informed record collectors understand that the sound quality isn't strictly from the medium. Most avid collectors such as myself have a great stereo/speakers that's responsible. That's why most of us understand that a Crosley isn't gonna make anything sound good. On that note I also think the analog vs digital argument is kind of a moot point. I don't know what "better" means among that peer group. I don't know what parameters they listened to their recorded samples nor who/how the samples were recorded and frankly have little interest in it. As far as engineers it's the archer, not the arrow. Peer studies would probably tell you Nirvana's Nevermind is a sonically better record than In Utero, but that doesn't make it a "better" record.
Regarding the toxicity, his "study" is pretty flawed and means nothing without context. According to a source below vinyl manufacturing accounts for less than half of a percent of PVC production, and that doesn't even get into how much PVC you're exposed to on a daily basis otherwise. And he's flat out wrong about manufacturers refusing to explore alternative measures to pressing. He clearly did his research with blinders on because there are studies available from before his video came out and I found this source with minimal effort. Wanting manufacturers in general to leave less of a carbon footprint is a reasonable desire but it is ultimately an exaggerated concern.

That's not to say the complete opposite is true but I take issue with environmental arguments that split these kinda hairs. I have no doubt that the components of a physical record aren't good for you. The same is probably true for most things in your home, and dare I say most foods you buy at the store, or most pieces of tech we carry around all day about 6 inches away from our ballsacks. I'll refrain from ingesting my record collection, but I honestly have little interest in that kinda micro doom speeches when there are vastly bigger fish to fry.
fair enough.
i agree he omits the fact that the some vinyl presses are trying more eco-friendly ways to press records. i just straight up googled "is there a eco-friendly way to press vinyl?" and got several articles and manufacturers shown. it's still over all not an ecofriendly way to produce records, they have to be shipped, too, which is unnecessary nowadays when you can download it as well.
concerning the quality. i don't think he was saying digital sounds "better", that's of course subjective, pretty sure he is aware of that. most people that say vinyl sounds better attribute it to warmth and dynamic. the latter has nothing to do with the medium though, more with how contemporary music is recorded and mixed. still, vinyl is the inferior information carrier if we are talking about that information getting lost or scrambled. i'd say vinyl is legit for archival purposes, since you can store it a heck of a long time.
as for me personally, i was an ardent defender of vinyl vs other mediums for the longest time, but at some point my record player broke, and i started getting flac versions of some records i wanted to listen to, and with the same setup of amp and boxes, was shocked how much nicer and clearer most of it sounded to me. i felt like i was living in a bubble the whole time. sometimes i miss the crackles and buzzing, but to me, high quality audio files is where it's at nowadays.
i am not too concerned about the health aspect, for the same reasons you described. we are surrounded by plastics all day, it's kinda dumb to make a point about vinyl. then again, i myself try to get rid of or avoid plastic products whenever possible, so personally why would i stop with the vinyl? i love looking at the covers, reading through booklets, but there's nothing preventing me from printing that artwork in the same format if i want to look at it. the whole process of listening to a vinyl record is also unenjoyable to me nowadays.
i will most likely keep my records or at least my most favored ones and those that aren't available online, maybe upload those myself and i still plan on getting a decent player again at some point, but honestly i haven't missed it too much, and since then, i often look at my humble record collection sitting there, collecting dust, and think i don't need this really. i can't see myself going back to vinyl, even if they invent green alternatives, because it's just clunky to me. nowadays i'd rather buy my music on bandcamp, it's great when artists can put out there music with minimal overhead. any physical medium, wether be for music, film or videogames, seems like a waste to me tbh. it's a luxury/vanity item to me. nothing wrong with that if you enjoy it, but i'd like to minimize my footprint and i actually rather pay 12 bucks for a digital album than the same amount for an lp, because the artist probably keeps more from that digital purchase than from the physical release that had to be produced and shipped everywhere. at the same time, i know downloading and streaming uses up energy and hardware as well and isn't necessarily climate neutral.
so that's why i overall agree with him, even if i accept that he went a bit doomer, especially on the health aspect. i wouldn't tell anyone to throw aways their vinyl, or tell them that's garbage, but as i grow older and out of some cliched views i held as i was younger, mostly informed by what i thought what is cool or what isn't, i realized i probably fetishized vinyl, too, because it was simply cool and different, not necessarily better or smarter. it's part of punk and hip hop culture in a way and that's the main reason i wanted to use it. it shows off a lot better than a music folder on your computer and makes for better conversation pieces. people are way more impressed in social situations when you tell them that you own the velvet under ground & nico early pressing on vinyl than by you knowing that record in and out, cause they can't see or prove that and it takes no effort to listen to em, but to hunt that lp down and have the money to pay for it.
that is another part i dislike about vinyl culture, not everyone has the funds to maintain that setup, or even the space for it. it's like with tattoos. everyone acts like it's some underground culture thing, but it's actually a product you buy. there is no reason to be proud about owning that edition or have tattoos from a great artist, because everyone who pays can do that. it says nothing about a persons merit, but for most people i feel like vinyl and tattoos(i have tattoos myself) are about projecting some sort of sophistication and low key wealth status. why else would broke ass people sacrifice their funds for this? i know so many people that are too broke for everything and complain all the time about it, but get tattoos, records or tech stuff liberally. i love tattoos and wish i'd have gotten more while i was young enough to have reaped the coolness points, but it makes no sense to me to not eat for a month just to get one, or get one vinyl record with a booklet that i will read once and then never again when i can buy two digital records for the price and let the artist keep more money.
don't want to offend any vinyl(or tattoo) lover on here, both things are rad and if that's what makes one happy, i'm all for it. but the whole myth of vinyl being the superb medium for music is total bullshit imo. it's the same thing like using some old ass handgrinder for your coffee and tricking yourself into thinking it makes the coffee taste better, when in reality that cheap ass old handgrinder probably grinds like shit and gives you carpal tunnel and a cheap electric spice grinder might yield better results, but is not so nostalgic and nice to look at.
one thing though i dislike sometimes about digital formats is it triggers my tinnitus way more than vinyl, or analogue sources in general. mostly on youtube and sources as such though.
